TS-PEU Universal Socket Power Extension for Modular TBUS - Product - Midwich

Kramer's TS−PEU is a power extension unit that includes six universal power sockets: one on the surface of the unit and five hidden neatly under the table. TS−PEU fits into TBUS inner frame modules with dual power socket openings.
To use the hidden sockets, simply pull TS−PEU out of the TBUS using the handles and lay it on the table. When not in use, carefully slide TS−PEU back into the TBUS.
